SCREEN-OPENING.

Specification of Letters Patent.

Patented Apr. 28, 1914.

Application filed October 12, 1911. Serial No. 654,348.

To all whom, it may concern:

Be it known that 1, CHARLES H. Pas- GHALL, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, -have invented certain new and useful Improvements'inScreen-Openings, of which the following is a specification.

My invention relates to improvements in screened openings, and has forits salient object to provide in association with a pivoted window sash,or the like, a screen structure arranged to permit the opening orclosing of the sash without interference with or ranged adequately toscreen the opening regardless of the extent to which the pivoted sash isopened.

In the drawing, wherein I have illustrated an embodiment of my inventionparticularly adapted for factory window or sky-light purposes, by way ofdisclosure of one form of the invention: Figure l is a perspective viewof a section of the structure; and Fig.

frame and screen.

in such drawing 5 indicates the frame, preferably of angle iron,providing a band 6, 6, to bound the four sides of the opening. Connectedwith said band, preferably integrally, are flanges 7 and 7',lyingrespectively in the planes of opposite edges of the band 6, 6, or, as Imay term it, along the interior and exterior planes, respectively, ofthe opening. For convenience the frame structure may be made of twopieces of angle iron with their body portions 6 and 6' meeting near themiddle of the vertical sides of the frame, the adjacent ends of theflanges 7, 7' being vertically separated a short distance to afford anopening 8 between them as shown in Fig. 2. The two sections of the framemay, of course, be duplicates in construction, reversely faced, and thetwo sections may be secured together in any suitable fashion.Specifically I prefer that all to channel bars 9 to receive sky-lightglass, or that other provision be made for the appropriate setting ofthe frame in its intended position. With the specific constructionshown, however, the two sections of the frame may adequately be securedtogether i by riveting them, as at 10, to the vertical chamber bar 9. Tothe flanges 7 at the edge 11, of suitable construction, coiiperatingwith complemental hinge members 11, se cured to the side frame membersof a swinging sash '12, suitably constructed neatly to close theapertures when swung to vertical or closed position, and, provlded withany suitable latch 13 for holding it closed. Manifestly, the arrangementof the flanges 7-7' leaves the sash 12 free to swing, as shown in Fig.1, from vertical closed position to horizontal fully open position, thesash 12 when fully opened lying horizontally in the opening 8 betweenthe flanges 7-7, as indicated in Fig. 2.

The screen is made of two sections, 14-1 i,' each preferablysubstantially coextensive with, and secured to, the correspondingflanges 77', so that the screen sections lie on opposite sides of thepivotal axis of the sash and confront opposite faces of the sash. Eachscreen may have a border frame 15, appropriate portions of which may beriveted, as at 16, or otherwise secured to the confronting, or inner,faces of the respective flanges 77. The contiguous frame members 15 oftwo screen sections may, if desired, be equipped with yielding fillerstrips 17 in the form of felt tubes, or the like, for exact contact withthe window glass at all times, but in commercial practice I find thatthe approximation to a fit aflorded by a straight-edge screen frame isusually sufficiently close for practical purposes.

It will be noted that, with an open hinge structure, as at 11,11, thesash may readily be lifted out of the frame, passing easily through thegap between the screens and the opening 8 between flanges 7, 7

While I have herein described in some detail a specific embodiment of myinvention, some details of which I may claim for their intrinsic noveltyand value, it will be understood by those skilled in the art thatchanges in the construction. may be made without departure from thespirit of my invention and within the scope of the appended claim.

VVhat I claim isr The combination of a frame bounded by angle irons,each angle iron having one of its flanges lying respectively in theplane of the rear or front face of the frame accordingly as it is aboveor below the center of the frame, and its other flange lying within theframe for attachment thereto to supof the opening 8 I provide hingemembers port the angle irons, upper and lower screen new melnliwrsrespectively secured t0 the inner faces of the rear and front flanges,whereby the flanges form protective borcters for the corresponding edgesof the screen members, 1 the secured edges'ef the screen members 1ying'in the corner between the flanges of the angle irons and the free edgesof said screen members being spaced apart horizontally :1 distancedetermined by thedistance be-' W tween the planes of the upper and towerflanges amt vertically a distance to accent I hand in the presence oftWo Witnesses.
